First, let's take a look at what is the resolution?
Resolution (resolution, RTHK called resolution) is the precision of the screen image, refers to the display can display the number of pixels. Because the dots, lines and faces on the screen are made up of pixels, the more pixels the monitor can display, the finer the

Due to the spread of spam, various anti-spam technologies have been proposed. Domain Name reverse resolution (rdns) is the most common type. More email servers need to check IP reverse resolution (PTR) records, especially foreign email servers, in many cases, the recipient rejects relay or cannot send the bounce message because there is no reverse resolution.However, for various reasons, for example, revers
Which of the following affects the definition of a movie? video bit rate, frame rate, and resolution?
Bit Rate: affects the volume, which is proportional to the volume. The larger the bit rate, the larger the volume. The smaller the bit rate, the smaller the volume.
Bit rate is the number of digits transmitted per unit time during data transmission. Generally, the unit is kbps, that is, a thousand bits per second. That is, the sampling rate. The large
Resolution
The first step in polishing a photograph in Photoshop is to ensure that the image has the correct graphics resolution. The graph resolution indicates the pixel value in a small rectangle, and describes an image and establishes the details. The resolution of a graph is determined by the pixel value or number
Video bitrate, frame rate and resolution exactly which one affects the sharpness of the movie
Code rate: affect the volume, proportional to the volume: the larger the rate, the larger the volume, the smaller the rate, the smaller the volume.
The bitrate is the number of data bits transmitted per unit of time when data is transferred, typically in Kbps, or thousands per second. That is, the sampling rate, the larger the sampling rate per unit of time,
This is a question worth discussing, the author believes that the 0 FFT can improve the frequency resolution, and give the test results, it can be seen that the frequency of the details of the observation ability, I can be sure that this test is a real experiment. But all the digital-signal textbooks say that the 0 FFT does not improve the frequency resolution, is not a contradiction.

Think each time by a variety of resolution name, proportion make a mess of it? Let's get you to know all the resolutions! The common screen proportions are actually only three: 4:3, 16:9, and 16:10, plus a special (but also common) 5:4.
4:3 Family
4:3 is the most common screen ratio, passed down from the television age to the old standard. In the modern wide screen before the rise, most of the screen
The current mainstream computer display resolution is 1920x1080, which is often said the FHD standard, but the smartphone is beginning to 2560x1440 forward, the PC monitor clearly needs further strengthening, the next generation standard is 4K resolution, that is, UTLRA HD standard. This year, Dell, Lenovo, Asus, Samsung and other companies have launched Low-cost 4K display, the cheapest only more than 4,00

Driver Installation:
The installation of a new video card driver is not perfect, that is, when the system is started, there is no visual pattern of the Progress circle, and it is very likely that the resolution can be properly displayed only by force modification, however, after the video card driver is installed, you can use the desktop special effects (Very dazzling) that come with the system. The default noveau has a visual progress circle, and the
Study of super-resolution reconstruction algorithm for compressed imagesSuper-resolution reconstruction is a high-resolution image reconstructed by one or more low-resolution images, such as reconstructed resolution 0.25m resolution
These are basic concepts, but the more basic the concept is, the more general it is, the less common this concept is in normal work, but sometimes I can't make it clear when I think of it or when someone asks.I searched the information on the Internet and it seems to be a little more detailed.1. What is pixel?
To put it simply, what we usually call pixels is the number of photoelectric sensing elements on CCD/CMOS. After a photosensitive element passes through photosensitive, photoelectric signa
